37 Claims. (Cl. 12-51) This invention relates to a machine for attacht ing a welting strip to a shoe and, as illustrated herein, is directed more specifically to a machine for adhesively uniting a precoated welting strip to the outturned flange of a shoe.

In one method of shoemaking the upper material, includingV the upper and lining, is threadlasted to a middle sole of canvas or similar material. .The surplus of the ange formed thereby is then trimmed off close to the bottom of the shoe at an angle to provide an abbreviated outwardly directed flange to which the welting may be attached. It is for adhesively attaching a welting to the flange of this type of shoe that the machine of the present invention is designed, and it is an object of the invention to provide for rapid, accurate application of the welting to the flange in such a manner as to insure an enduring bond between the welting and flange.

The narrow surfaces of the flange and welting strip afford very little bonding area. Consequently, both surfaces are precoated with cement, the upper surface of the flange being roughed before the application of cement thereto to remove the finished grain surface to which cement will not adhere perfectly. The cement applied to the beveled flange is extended over the lasting thread and thread holes to avail of all possible bondlng area. Consequently, to take advantage of this and in order to insure proper adhesion between the flange and welting, care must be taken to press the precoated inner or apex edge of the beveled portion of the welting well up into the crease between the flange and upper.

application Serial No. 350,493, filed August 3, 1940, in the name of Fred L. Ayers, the welting and flange are progressively adhesively united by a pair of feed rolls, a portion of one of the feed rolls being adapted to project into the crease adapted to project into the crease between the flange and bottom.

While the operation may be performed with facility along the sides of the shoe, the contour at the toe is such that the welting crinkles and .35 In accordance with the practice described in I does not lie flat in the crease. Accordingly, an- 55 other feature of the invention resides in the combination in a machine of this character of means for progressively pressing the welting into engagement with the flange 'of the shoe and means for forming slashes in that portion of the welting which will surround the toe of the shoe before it is applied to the shoe so that when attached it will lie flat in the crease Vbetween the flange and upper.

When the welting has been laid completely about the shoe, it is desirable to sever the attached portion from the unattached portion. Consequently,v another feature of the invention lies in the combination in a machine of this character of means for severing the welting and of means for supporting the welting during the severing operation so that it will not be pushed aside without being cut.

In order to prevent damage to the shoe when the welting is severed, for example, by contact of the severing knife with the upper, the operator generally draws off an'appreciable length of welting before he severs the same. Because of this, a considerable length of welting projects from the feed rolls which must be moved back between the rolls if it is to be acted upon by the feed rolls to press it onto the flange when the succeeding shoe is presented to the feed rolls. This is effected in the present machine by meansfor retracting the unattached welting a sufficient distance after it has been severedv so that its free end is substantially at the bite 'of the feed rolls.

The objects of the present invention having been described generally, the specific construction and operation will now be described in detail with reference to the drawings, in which Fig. 1 is a side elevation of the machine;

The illustrated machine comprises a pair of feed rolls I and I2 which are constructed and arranged progressively to press a precoated welting strip W against the precoated surface of the bottom flange F of a shoe S (Fig. 3) and into the crease between the flange and the upper, a slasher I4 (Fig. 5) for slashing that portion of the welting strip which is to extend about the toe of the shoe, a severing knife I6 (Fig. 6), and a gripper I8 for holding the welting strip during the severing operation, and a retractor 2D (Fig. 1) for pulling back the free end of the unattached severed welting so that at the beginning of each operation the free end of the welting will be substantially at the bite of the rolls Il) and I2.

The feed rolls Ill and I2 are mounted on a head 22 which is tilted at an angle: of approximately 35 to the horizontal on the upperend of a supporting column 24. The angular position of the head brings the feed rolls I0 andrl2 into a convenient position for the operator. The lower roll I0 serves not only as a feed roll but also as a sup port and presser roll and is provided with a frustoconical surface and the work-engaging portion thereof occupies a substantially horizontal plane so that the lower face of the flange F of the shoe rests against this surface with the shoe tilted at an angle, as illustrated in Fig. 1, thereby permitting the operator to have a clear view of the progress of the welting W as it is applied to the flange. The large end of the roll I I) terminates in a peripheral bead ID' (Fig. 3) which projects upwardly from the frusto-conical surface thereof for a purpose which will appear hereinafter. The roll I0 is fixed to a shaft 26 which is journaled in an arm 28 pivotally supported at 30 in the head 22. A sprocket 32 is fixed to the inner end of the shaft 26 by which the shaft, and consequently the roll l0, may be driven, as will appear hereinafter. The upper feed roll I2 serves as an abutment over which the welting travels and against the resistance of which the roll I0 holds the shoe with its flange F pressed into engagement (Figs. 3 and 8) with the beveled surface of the welting W, and to this end, the roll I2 is provided with a frusto-conical surface (Fig. 9) the work-contacting portion of which is substantially parallel to the co-operating portion of the frustoconical surface of the roll ID. the larger end of the roll I2 being arranged so that it projects into the crease between the flange and the upper to guide and force the inner or apex edge of the welting as far as possible into this crease. When the rolls are in operative position (Fig. 8) the bead I0 on the roll I0 projects into the crease between the flange and bottom along the thread line of the inseam. The crest of the bead acts partly as a guide, and because it lies in the plane of the end of the roll I2, it also insures an unyielding pressure between the fiange and welting at the innermost edge of the welting. The roll I2 is journaled in a bracket I2 (Fig. 4) fixed to the end of an arm 34 which, in turn, is fixed at its inner and to the face of the head 22 substantially parallel to the arm 28, and is driven from a shaft 34 housed in the arm 34 by means of gears 35 and 35 (Fig. 9). 'Ine shaft 34' has fixed to its inner end a sprocket 36 (Fig, 1) which is connected with the sprocket 32 by a chain 3S' whereby the rolls I0 and I2 rotate together andin opposite directions. The shaft 34 is driven from a constantly rotating shaft i60 by means of meshing gears |62 and 164, the former being Xed to the shaft |60 and the latter being fixed to the shaft 34' (Fig. l).

In order to grip the work and forcibly to press the flange into engagement with the welting, the lower roll I0 is normally urged toward the roll I2 by means of a spring 4 I, the distance between the rolls in operative position being xed by means of a stop 38 (Fig. 1) mounted on the fixed arm 34, the end of the stop abutting the arm 28. This distance may be varied by adjustment of the stop 38. A treadle rod 40 is provided for lowering the roll ID so that the work may be placed between the rolls, and to this end, the rod is attached to an arm 42 fixed to the arm 28 and extending rearwardly thereof whereby the arm 28 may be tilted about its pivot 30.

The welting W which has been previously coated with adhesive along its beveled edge is supplied from a reel (not shown) and led vertically downward therefrom to the entrance side of the feed rolls I0 and I2, the free end e of the welting extending between the rolls and being held substantially taut by the same, as illustrated in Fig. 5. The welting is guided over the surface of the roll I2 by means of guides 43 and 45 (Figs. 2 and 8). The guide 43 holds the welting against the peripheral surface of the roll I2 and is provided with a finger 43 parallel to the end of the roll which engages the inner or apex edge of the welting and prevents it from riding off the large end of the roll. The guide 43 is adjustably mounted at 41 (Fig. 8) and may be moved transversely of the surface of the roll I2 in accordance with the width of the welting. The guide 45 (Fig. 2) substantially conforms to the surface of the roll I2 and is disposed adjacent to the lower side thereof (Fig. 8). A projector 44" extends upwardly around the front side of the roll and serves to facilitate introduction of the welting between the guide and roll. The guide 45 is provided with a tooth 45' which projects toward the surface of the roll at the small end and is adapted to engage the outer square edge of the welting to hold the welting with the inner or apex edge of its beveled portion in coincidence with that portion of the edge of the roll I2 which projects into the crease between the flange and upper. The guide 45 is also adjustable widthwise of the roll to accommodate different widths of welting, being held in position by a screw 44 (Fig. 8).

Heretofore, when welting has been applied to a shoe, it has been necessary to slash it obliquely and to beat it after it was attached in order to straighten it so that it would be in the proper position for the application of the sole thereto. It has been found, however, that when the welting is slashed throughout its entire length that portion of the welting which extends along substantially straight runs of the shoe appears to be somewhat ragged. Around th'e toe and any other sharp bends, this raggedness is not as noticeable, due to the fact that longitudinal stretching of the welting at these points tends to close the slashes so that they do not show. In order to eliminate this ragged appearance along the straight portions of the shoe, it is proposed to slash the welting only along th'at portion thereof which is to surround the toe of the shoe and to leave the remainder of the welting unslashed. To this end, a Slasher I4 (Fig. 5) is provided in the present machine which may be brought into operation at such a time during the application of the welting to the shoe that only that portion of the welting which is to surround the toe will be slashed. The Slasher I4 consists'of a two-bladed cutter 44 fixed to the end of a shaft 46 which is journaled in an arm 48 pivotally mounted at 50 on a bracket 52 bolted to the head 22. A pulley 54 is fixed to the end of the shaft 46 and is constantly rotated by means of a belt 56 which is connected with a pulley ||8 (Fig. 4). A knee-operated rod 58 is secured to the arm 48' at 60 and provides means for tilting the arm 48 in a clockwise direction about its pivot 50 to bring th'e cutter 44 into engagement with the flesh or beveled side of the welting. The cutter in its active position lies in a plane at substantially 45 to the plane of the welting so that the slashes are at approximately 45 to the surface of the welting. A spring (not shown) normally returns the cutter and the arm 48 to an inoperative position. The depth of slash made by the cutter may be varied by limiting the downward movement of the arm 48. This is accomplished by providing a boss 48 on the back of the arm 48 to which there is xed a pin 49'. The free end of the pin 49 co-operates with a slot 49 formed in a bracket 5|. A screw 5| at the end of the Aslot limits the downward movement of the pin 49 in the slot.

The unsupported length of welting between the source of supply and the feed rolls is so exible that means must be provided for holding it during the slashing operation and, consequently, a combined guide and support 68 (Fig. 5) is provided. The guide and support 68 forms a part of the bracket 5| which is screwed to the end of the arm 34. The guide and support is provided with a vertically extending passage I0 th'rough which the welting passes on its way to the feed rolls. An angular slot 12 (Fig. l) is formed in one wall of the passage for the reception of the ends of the cutter blades as they slash the welting.

As is evident, the slashing operation is carried out during the appli-cation of the welting to the shoe but before the slashed portion of th'e welting is applied to the shoe. Due to variation in the sizes of shoes, it is impractical to employ gaging means for determining when to begin the slashing operation and when to end it in order to obtain slashing along that portion of the welt which is to surround the toe. It has been found, however, by experiment, that the proper slashing can be obtained for any size shoe by bringing the slashing knife into operation at about the same time that the welting is being pressed into engagement with the ball of the shoe and continuing the slashing until the welting h'as been applied to a point just short of the toe of the shoe, whereupon the slashing should be discontinued. If the slashing is carried out during this period of application of the welting, the slashed length' will coincide with the toe portion of the shoe. Sometimes it happens that an especially deep shank is employed in a shoe. When this is so, it is desirable to slash the welting so that it will lie fiat along the bend between th'e shank and ball. This may be accomplished by bringing the slasher into operation a little past the breast line and continuing it to a point about half way out of the shank.

After the welting has been applied about the entire shank and forepart of the shoe from breast line to breast line, the attached welting must be severed from the unattached portion of the welting. To this end, a reciprocating knife I6 (Figs. 4 and 6) is provided. When the welting is to be cut, the operator normally pulls the shoe away from the feed rolls, to the left in Fig. 1, a substantial distance so that a free length of welting will be exposed for severing, and also to remove the shoe from therange of the end of the knife so that th'e upper will not be damaged. This free length of welting must be 'supported during the cutting operation and, consequently, a gripper I8 is provided for gripping the welting adjacent to the cutter and holding it during the cutting operation.

The gripper I8 is mounted for reciprocation to and from the welting on a line parallel to the axis of the roll I0 and is supported by a web 14 formed integral with the arm 34 (Fig. 6). The gripper comprises a pair of jaws 16 and 18 (Fig. 61), the jaw 16 being fixed to a slide 80 which is mounted in a dovetail groove 02 formed in the web 14. A gib 14' forms one side of the dovetail groove and is screwed to the web at 15. 'I'he jaw 18 is pivotally mounted at 8| on the slide 80 and the reciprocation and closing of the jaws are accomplished as follows: the inner end of the slide is connected by means of a link 84 (Fig. 1) to a lever 86 which is, in turn, connected to a lever 88 the free end of which is provided with a cam roll 90 which occupies a cam groove 92 formed in one face of a cam 94 (Fig. 10). The lower jaw 18 is connected by means of a rod 96 to the end of the lever 86. When the cam is rotated, the counterclockwise motion of the lever 86, as seen in Fig. 1, at first gives a forward motion to the slide 80 so as to move the jaws toward the welting strip. As

the slide moves forward, the link 84 is turnedk about the end of the slide 80 as a center and the proportions of the link-are such that when the gripper moves into the plane of the welting, the rod 96 will be moved forward to close the lower jaw. In this position the link 84 is substantially in line with the slide 80 on a dead center so that the jaws are locked in position. The cam track 92 is so formed that the jaws remain locked during the cutting operation, which will be described hereinafter, and thereafter are released and withdrawn for a subsequent operation.

I'he knife I6 (Fig. 6) is reciprocated in a manner similar to the gripper I8 and consists of a bar |00 beveled at its outer end to provide a cutting edge, the bar being slidably mounted in a dovetail groove |02 formed in the outer surface of the slide 80 so that it slides with the jaws to and from the welting strip. To provide for further movement of the knife, that is, cutting movement during the time the jaws are gripping the welting, the inner end of the bar |00 is connected by means of a link |04 and a lever |06 to a lever |08 (Fig. 4), the latter being connected to a lever ||0 having a cam roll ||2 at its free end which rides in a groove ||4 formed in the opposite face of the cam 94. The lever |06 is pivoted at |06 on the end of thebar |00 and is slidably connected to the lever |08 by a pin ||6 and groove IIB so that during the initial forward movement of the gripper I8 the knife I6 remains inoperative. When the gripper has moved forward far enough to grip the welting, the cam 94 begins to turn the lever |08 in a counterclockwise direction, as seen in Fig. l, which, in turn, moves the lever |06 in a clockwise direction so as to force the bar |00 forward and thereby passes the cutting edge of the knife through the welting strip. The cam track is so formed that the knife is irnmediately withdrawn toa position for a subsequent operation. The gripper I8 and knife I6, as described above, are operated by the cam 94 (Fig. I0) which is intermittently driven by a one-revo'- lution clutch ||5 (Fig. 11) connecting it with the hub of the constantly rotating pulley 8. The pulley ||8 is fixed to a shaft I 66 which is driven from'the Shaft, we er a Pair Qfbevel gears |68 and |10 (Fig. 4). The caniM` ismounted to turn freelyon the shaft |66 and-may be connected to thehub o f the pulley by aspiring-pressed pin I I5 which is housed; in a recess IIJ `formed in the hub of thev cam. A recess II'Il is formed in the hub of the pulley, and when the recesses I II and I I'I are opposite, the en dof the pin I I5' is pressed into the recess |.|`I, thereby connecting the pulley and cam. A nub II=9 is fixed to the pin II5 and extends from the hub. of the cam through a slot II 9. The pin H5' is withdrawn from the recess ||'I, by means of a cam |2| which is lixed to a bar |20 which may be moved into the path of the nub Il!) by meansof the treadle |20. When the treadle is depressed, the cam I2I is moved out of the path of the nub |I9 and the pin |I5 snaps into, the recess I I1, thereby locking the hub of the pulley to the hub of the cam. Upon release of the treadle |20 the cam |.2I is moved into the path of the nub IIS and as the nub moves into engagement with the cam I2I the pin I I5 is-withdrawn from the recess I I 'I' to disengage the drive between the pulley IIB and cam 94. To prevent oyerdrive by reason of momentum of the cam 64, a spring-,pressed brake |22 (Fig. 4) is mounted in a boss |245` formed on the head 22 which is adapted yieldably to engage the peripheral surface of the cam 94. The braking action may be increased or decreased by adjusting a screw |26.

As heretofore indicated, when the welting has been severed, a substantial length thereof projects from the forward side of the feed rolls. If this projecting piece is not retracted when another shoe is presented to the rolls, the free end y I e of the welting will not be pressed by the rolls into engagement with the flange of the shoe and will consequently constitute a waste end which must be cut oi. To eliminate such waste and to insure the proper adhesion of the leading or free end of the welting and the ange, it is desirable to draw the welding back between the rolls I and I2 so that its free end e is substantially at the bite of the rolls in position to have the flange pressed into engagement therewith (Fig. To this end, a retractor 20 is provided which consists of a pair of jaws |26 and |28 (Fig. '7) which are disposed in open position on opposite sides of the welting above the slasher, as shown in Fig. 1. The jaws are carried by an arm |30 which is pivotally supported at |32 on a bifurcated stud |34 projecting from the top side of the arm 34. The arm |30 is connected (Figs. 1 and 5) by members |36, |38, |40 and |42 to the treadle rod |20 by means of which the arm |30, and consequently the retractor 20, may be moved a predetermined distance along the welting W. The distance through which the retractor 20 is moved along the welting is equal to the length of welting which will normally be drawn oi by the operator when he severs the attached welting from the unattached welting. Consequently, when the retractor 20 is moved downwardly along the welting by means of the treadle rod |20 and is caused to grip the welting, as will be hereinafter described, and is then released so that it moves back to its original position, it will retract the welting so that the free end e thereof will occupy a position substantially at the bite of the feed rolls. The retractor 20 is normally held in its inoperative position by means of a light spring |46 surrounding the link |38 with its ends abutting a collar |46 fixed to the link |38 and the end of the member |40, the latter being movable longitudinally of the link agrege.

|38.- BY depressies the treadle rod 12,0, the laws |26 and |28 (Fig. 7) arebrought down into gripping position. If the treadle is immediately released, the jaws will remain in their gripping position and the member |40 will merely compress the light spring I 46. As soon as the welting is cut, however, the spring I4S^will return the retractor 20 and the welting to their initial positions. The jaw |26 is xed and the jaw I 28 is pivotally mounted on the arm |30 at |48. The pivoted jaw |28 is moved into and out of grippingv relation with the jaw |26. by a cam |50 which is screwed tothe end of a bracket |52, the latter being fixed to the. top side of the arm 34. The cam |50 consists of a hollow frame having an irregular track |54,'show'n'in Figs. 4 and 6, with one side or the other of which the tail end |56 of the movable jaw |28,is held in engagement by a spring-pressed' beveled'pin |58. As the retractor 20 is moved downwardly along the welting, the tail end of the jaw |28 moves downwardly along the left-hand side of the track, being held in engagement therewith by the spring-pressed pin |58. At the lower end of the track the jaw |28, is moved by the inwardly directed portion of the Ltrack about its pivot point lto close against the jaw |26. The spring-pressed pin |58 is mounted in the arm |30 and projects into the path of the tail end |56 of the jaw |28 so that as the jaw is biased to a closed position the tail end of the jaw is` moved past the springpressed pin |58v and is held thereby against the right-hand side of the track. When the treadle |20 is released and after the welting has been severed, the gripper 20 moves upwardly along the cam track |544' and, as it approaches the top, the inwardly directed portion of the track moves the tail end |56 of the jaw |28 to the opposite side of the spring-pressed pin |58, thereby releasing the welting and holding the jaw in an open position.

To apply the welting to the flange of the shoe, the operator separates the -feed rolls by raising the treadle rod 40 and rests` the flange of the shoe on the depressed roll I0 and then releases the treadle rod 40 so. that the upper surface of the flange is brought squarely' into contact with the beveled edge of the welting, which liesaround the periphery of the presser roll I2, as illustrated in Fig. l. The rotation of these rolls carries forward the work,v which the operator must guide, making sure that the apex` of the welting is pressed as far as possible into the groove between the flange and upper. When the work progresses to the point where the welting is being applied tothe ball, the operator then depresses the kneeoperated rod 58 for bringing the slasher I4 into operation and holds this rod down until a point short of the toe of the shoe is reached, whereupon he releases the rod. The operator continues to guide the shoe betwen the rolls until the welting is laid completely around the shoe from breast line to breast line. In order to sever the attached welting from the unattached welting, the operator pulls the shoe away from the feed rolls a short distance, so as to to expose a short length of welting, and then actuates the treadle rod |20 which cocks the retractor 20 and by the rotation of the cam 94 simultaneously bringsthe gripper I8 and severing knife I6 into operation. As soon as the welting is severed, the spring |46 returns the retractor 20 to its initial position, thereby withdrawing the welting so that the free end thereof is substantially at the bite of the rolls so that it will be in proper position for application to the next shoe presented. n
